Answer:
area is 26.285cm² permiter is 28.565 cm
Step-by-step explanation:
area
so split the shape into smaller shapes
half- circle
area of a circle is πr^2 so πx4^2 is 12.57 so half this number to get area of a half- circle =6.285cm2
rectangle area = (2+4+2) x 1= 8cm2
triangle area is 1/2 base x height
so 1/2 8 X 3 = 4 x 3= 12 cm2
add them all up 6.285 + 8 + 12= 26.285cm2
perimeter
do it bit by bit again
perimeter of half circle
for full circle =2πr^2 so = 25.13
for half circle= 12.565cm
rectangle part = 2+2+1+1 = 6cm
triangle part =5+5 = 10cm
total perimeter = 12.565+6+10= 28.565 cm
